It is recognized that in some instances a person or public agency performing a public service may need to undertake emergency development to protect life and public property, or to maintain public services before the provisions of the Subchapter can be fully complied with. Where such persons or agencies are authorized to proceed without a permit pursuant to Public Resources Code Section 30611, they shall comply with the requirements of Public Resources Code Section 30611 and Section 13144(a), and to the maximum extent feasible, with the other provisions of this Subchapter. The person or public agency performing the emergency work shall apply for a follow-up regular permit to authorize the development undertaken to address the emergency.
